Carpet or rug is a good suggestion. For me, I heard the biggest improvement besides bass traps when I treated the first reflection points on the side walls with diffuser panels. Actually, GIK sells stuff that acts as a combination of diffuser and absorber.
Acoustic treatment
I need some advice on how to proceed with acoustic treatment in my listening room. Setup is Wharfedale Jade 3, Cambridge CXA-81, Bluesound Node 2i, SVS sub. Stands are damped with pea gravel and sit on needles on metal disks. Speakers sit on dense foam isolation pads. They are 30" from the front wall and 40" from the side wall. Room is about 15x13x8. On certain music (Hawaiian slack guitar, some soft piano jazz) I seem to get resonance around the bass/mid crossover at 350 hz, perhaps a little higher. Otherwise I am very pleased with the sound. I have acoustic panels on the front wall behind the speakers and two DIY tube traps that I've moved to various locations. Here is my question: assuming that the room is the problem, should I look in the direction of absorbtion (i.e., a resonator tuned to the 300-500hz range) or dispersion? Thanks.

I have a thick oriental carpet on the floor. Following geof3's recommendation, I put my tube traps at the side first reflection points with the foil half toward the speakers, thus acting as a diffuser for mid and higher frequencies. It definitely helped, so as I suspected I have a reflection problem. Chipping away at the problem, which is part of the fun. I'm sure that Townshend isolation pods are great products, but before I spend $1300 on a set I'm going to spend a few hundred more on taming the reflections in my room. Thanks for the good advice. |

To update everyone on this thread, I went over the SVS sub set up, lowered the crossover frequency and played a lot with the phase setting. Incorrect sub setup was the cause of most of the mid-range resonance. I did order some IsoAcoustic pucks to put between the speakers and the stands. We'll see how much they add, but the real issue was sub set-up. Thanks again for the advice. |
